Answer:
1) B/ 0.4n = 12; n = 30
2) B/ 125 – x = 58
3) B/ $1.75
Step-by-step explanation:
1) 0.4n = 12
n = 12 ÷ 0.4
n = 30
2) 125 – x = 58
– x = 58 – 125
– x = – 67 ( – & – will get cancelled)
x = 67
a) 125 + x = 58
x = 58 – 125
x = – 67 (pages won't be in negative)
c) 125 ÷ 58 = x
2.15 = x (wrong)
d) 58 – x = 125
– x = 125 – 58
– x = 67
x = 67 ÷ –1
x = – 67 ( pages won't be in negative)
3) 12x = 21
x = 21 ÷ 12
x = 1.75
The answer is B; $ 59.00. All you have to do is multiply the price times 4 and then subtract that from 100. Then do it again and 59 should be your answer.
Answer:
9 feet
Step-by-step explanation:
Area of a parallelogram = base times height
Thus, 54 = 6h
where h = height
* divide each side by 6 *
54 / 6 = 9
6h / 6 = h
h = 9
Thus, the answer is A
Mutiply each by four to get n=-49.6. Hope this helped.
